This paper explores the emergence of norms in agents’ societies when agents play multiple -even incompatibleroles in their social contexts simultaneously, and have limited interaction ranges. Specifically, this article proposes two reinforcement learning methods for agents to compute agreements on strategies for using common resources to perform joint tasks. The computation of norms by consider...

In this paper, we introduce the notion of an action $Y_X$as a generalization of the notion of a module,and the notion of a norm $vt: Y_Xto F$, where $F$ is a field and $vartriangle(xy)vartriangle(y') =$ $ vartriangle(y)vartriangle(xy')$ as well as the notion of fuzzy norm, where $vt: Y_Xto [0, 1]subseteq {bf R}$, with $bf R$  the set of all real numbers. A great many standard mappings on algebr...

BACKGROUND/AIMS Psychometric Hepatic Encephalopathy Score (PHES) and EEG are used to detect minimal hepatic encephalopathy (MHE). We aimed at standardizing PHES in Italy and comparing Italian, German and Spanish norms in EEG characterized cirrhotic patients. METHODS PHES was standardized on 228 normal individuals. Repeatability was studied in 128 individuals. One hundred patients with liver c...

Social norms help people self-organizing in many situations where having an authority representative is not feasible. On the contrary to institutional rules, the responsibility to enforce social norms is not the task of a central authority but a task of each member of the society. “The social norms I am talking about are not the formal, prescriptive or proscriptive rules designed, imposed, and ...

Conflicts between norms are a common problem in open Virtual Organisations and has to be dealt with. Norm-governed agents that populate such VO’s can remain operational only if they are able to resolve such conflicts. In this paper, we discuss how norm-governed agents based on the NoA architecture identify such conflicts and how the NoA model of norm conflicts can inform a re-negotiation of con...

Since Becker (3), a common argument against asymmetric norms that promote minority rights over those of the majority is that such policies reduce total welfare. While this may be the case, we show that there are simple environments where aggregate sum of individual utilities is actually maximized under asymmetric norms that favor minorities. We thus maintain that without information regarding i...

Price-based interventions can be corrective where users extract from a common resource, but may also impact existing social norms, often crowding them out. In contrast, I find a pumping tax implemented by a group of irrigators in Southern Colorado effectively crowded-in pro-conservation norms, enhancing the financial incentive’s impact. Using a unique, spatially oriented panel-data set of groun...
